Definitions
- the invention relates to a device for soil stabilization in hydraulic engineering, consisting of rods assembled into mats, which can be anchored to the ground at least by gravity, with artificial grasses attached to them, the rods being joined together to form a mesh having a mesh.
- a device of this type for securing against scouring of foundation structures of river and sea construction is known from DE-GM 82 31 725.9.
- the object of the invention is now to improve a device of the type specified in the preamble of claim 1 in such a way that a simpler and more reliable positioning of the grass holders to one another than previously possible can be achieved, while simplifying and making the production, and there should also be the possibility of one each to be able to preselect the cheapest arrangement of the grass holders to one another.
- the solution to this problem is characterized by a steel mesh mat, on the rods of which pre-made, rod-shaped grass holders are attached.
- Such a mat, covered with grass holders, does not allow the grass holders to change position relative to one another due to the permanent and rigid connection of their rods. Nevertheless, the mat to be laid flat on the bottom of the water can adapt to a certain degree to the more or less undulating water bed.
- the device described above is also characterized by significantly lower manufacturing costs because conventional structural steel mesh mats can be used for this purpose.
- the structural steel mesh mat has bars crossing at right angles and preferably the meshes of the structural steel mesh mats are each delimited by bar sections of at least approximately the same length, and the length of a rod-shaped grass holder approximately the clear distance between opposing bar sections Structural steel mesh mat corresponds.
- a particularly favorable embodiment both with regard to the manufacture of the grass holder itself and with regard to the connection between the grass holder and the structural steel mesh mat, which also ensures a secure position of the grass holders relative to one another, is characterized in that the grass holders each consist of a first profile bar, channel-shaped profile and one there is at least approximately the same length clamped in the channel of the first profile bar and surrounded by the grasses second bar and that devices are arranged on the channel-shaped bar for connection to the structural steel fabric mat.
- connection seals are molded onto the channel-shaped first rod.
- connection devices should be hook-shaped and the rods of the structural steel mesh mat should preferably be formed comprehensively with a clamping effect.
- a preferred and particularly inexpensive embodiment is characterized by a first, extruded, channel-shaped profiled rod, in particular made of plastic, with a profile part which is molded onto it and extends over its entire length, has a hook-shaped profile and can be clamped onto a rod of the structural steel mesh mat.
- the clear cross section of which corresponds at least to the cross section of a structural steel mesh rod that crosses the structural steel mesh rod to which the grass holder is attached.
- the devices for connecting the grass holders should be arranged on the long side of the grass protruding from the groove of the first channel-shaped rod.
- a preferred embodiment of this is characterized in that the second rod encompassed by the grasses is profiled in an annular shape and that the groove of the first profile rod is adapted to the profile of the second rod in such a way that that the first profile bar includes the second profile bar including the grasses by more than 180 °.
- Figure 1 shows a part of a device for soil stabilization in hydraulic engineering in a perspective view.
- Figure 3 seen details of the same on an enlarged scale along the line III-III of Figure 2;
- a common feature of all the embodiments is a rectangular structural steel fabric mat 1 composed of longitudinal bars 2 and cross bars 3 which cross at right angles, and of grass holders 4 fastened to the aforementioned bars.
- the bars 2 and 3 are non-detachably and rigidly connected at their crossing points.
- longitudinal bars 2 are directed parallel to the longitudinal sides and the transverse bars 3 to the transverse sides of the rectangular structural steel fabric mat 1.
- the bars 2 and 3 each have the same circular cross-sections over their entire length.
- grass holders 4 are provided, each of which is extruded from a first Rod 5 and a second rod 6, which is designed as a round rod section.
- a large number of artificial grasses 7 made of floatable plastic are attached to the grass holder 4 and distributed over their length, preferably in the form of flexible strips.
- the first rod 5 is profiled in a channel-shaped manner and has, on the outside on the longitudinal side facing away from the channel, a molded-on profile part 8 which extends over the entire length of the rod and is hook-shaped.
- the groove of the rod 5 is dimensioned and designed so that it includes the rod 6
- Grasses 7 under clamping force includes more than 180 ° of the rod 6.
- the hook-shaped profile part 8 is on one of the rods 2 or 3 of the steel mesh
- the length of a grass holder 4 corresponds to the distance between two adjacent and mutually rectified rods 2. 3 vpneiraider, so that the grass holder 4 is supported with its end faces on the aforementioned rods and is therefore fixed in the direction of its longitudinal extension.
- This configuration allows the grass holder 4 to be formed longer than the width of a mesh 10 of the steel mesh mat 1.
- the longitudinal and transverse bars 2 are respectively. 3 arranged at the same level to each other.
- grass holders 4 are fastened to each longitudinal rod 2 of the structural steel mesh mat 1, namely per row with a mesh-wide spacing from one another, the grass holders 4 being aligned in the same direction as the longitudinal rods 2, while according to FIG. 6 all transverse rods 3 are similar to those in FIG. 5 are occupied with grass holders 4.
- grass holders 4 are fastened to both the longitudinal rods 2 and the transverse rods 3, a mesh-wide distance being provided between the individual grass holders.
- the grass holders 4 are arranged in such a way that a plurality of grass holders 4 which are arranged one behind the other in the longitudinal direction of both the longitudinal and the transverse bars form quadrilaterals.
- grass holders 4 are each arranged to form a square, but the corners of this square are free of grass holders.
- grass holders 4 are fastened to every second longitudinal rod 2 and to every third transverse rod, a distance being provided between the grass holders 4 fastened to the longitudinal rods 2, which is twice as long as a mesh size, while those to the Cross bars 3 attached grass holders 4 are arranged with a mesh spacing from each other.
- the cross bars 3 are occupied with grass holders 4, which are located between the grass holders 4 of the longitudinal bars 2.
- the grass holders 4 are arranged approximately in a herringbone pattern, the grass holders 4 fastened to the cross bars 3 being offset in steps by a mesh size and the grass holders 4 fastened to the longitudinal bars likewise in the transverse direction of the structural steel mesh mat 1 each over a mesh width up or are arranged offset downwards.
- each grass holders 4 complement each other to form a square, the side lengths of this square each being twice as long as a grass holder and the grass holders 4 being arranged in the circumferential direction of the square with a mesh-wide distance from one another.
- the structural steel fabric mats 1 are separated longitudinally or transversely into relatively narrow strips and these strips are connected to one another in such an articulated manner that the structural steel fabric mat 1 can be rolled up for transport.
- Interlocking rings can be arranged on the rods of the structural steel mesh mat strips as articulated connections, preferably molded on.
- the articulated connection of the steel mesh mat strips can also be done by means of flexible organs, e.g. using ropes. This configuration also enables an even better adaptation of the installed structural steel fabric mat 1 to a wavy water bed than before.
- the to the rods 2 or 3 attached grass holders 4 can around the rods to which they are attached, in a certain sense by overcoming the clamping force
- Hinges so that they are roughly aligned during transport to the level of the structural steel fabric mat 1 and consequently the entire device requires less transport space than previously.
